Comparative Study of the Effect of Electrochemically Activated Water Solutions on Pseudomonas aeruginosa

Studies have been carried out to determine the sensitivity of Pseudomonas aeruginosa to activate aqueous solutions (anolytes and catholytes) in vitro. The solutions were obtained by electrochemical activation of water with 0.8% NaCl, as well as with combination of 0.4% NaCl and 0.4% Na2CO3 and were tested at final concentrations of 50% and 100%. The disinfectant Virkon S was used as a control. After different intervals of exposure of a P. aeruginosa suspension with a final concentration of 106 cells/ml to the action of the solutions, samples were seeded on Cetrimide agar and cultured for 24 hours at 37°C. An inhibitory effect on P. aeruginosa was established depending on the type and final concentration of the activated solutions. Electrochemically activated aqueous solutions with 0.8% NaCl, as well as 0.4% NaCl and 0.4% Na2CO3 exert inhibitory action on a P. aeruginosa suspension with a concentration of 106 cells/ml
